Generate a strong, random password with the character types and length you choose — created entirely in your browser.
This tool builds each password character-by-character using your browser's cryptographically secure random number generator, then shuffles the result. Nothing is sent to a server — the password only exists in your browser, and refreshing the page clears it.
A randomly generated password is only useful if you can retrieve it later. Consider using a password manager to store it securely rather than writing it down or reusing it from memory.
Choose your desired password length using the slider or input field, then select which character types to include — uppercase letters, lowercase letters, numbers, and symbols. Click Generate, and a new random password appears instantly. If you're not happy with the result (for example, if it's hard to read or type), simply click Generate again for a new one — there's no limit to how many times you can regenerate.
Every additional character in a password multiplies the total number of possible combinations an attacker would need to try, which is why length has a bigger impact on security than character variety alone. A 16-character password using only lowercase letters is generally harder to crack through brute force than an 8-character password using every character type, simply because of how exponentially the total possibility space grows with each added character. That said, combining length with variety (uppercase, lowercase, numbers, symbols) gives the strongest protection, since it maximizes both the character pool size and the total length together.
A brute-force attack works by systematically trying every possible character combination until the correct password is found. Modern computing power, especially with specialized hardware, can attempt billions of combinations per second for offline attacks against a stolen password database. This is why short or predictable passwords can be cracked in seconds or minutes, while a sufficiently long, random password can take longer than a human lifetime to crack through brute force alone — the math of combinatorial growth makes length an extremely effective defense.
Passwords based on real words, names, or predictable patterns (like "Password123!" or a pet's name plus a birth year) are vulnerable not just to brute-force attacks but to dictionary attacks, which test common words, phrases, and known password patterns first, since these tend to be far more likely than a truly random string. A password generated entirely at random — with no underlying word, pattern, or personal reference — has no such shortcut for an attacker to exploit, which is why security professionals consistently recommend generated passwords over self-created ones, even though generated passwords are harder to memorize.
The tradeoff with strong random passwords is that they're difficult or impossible to remember, especially if you're using a different one for every account (which you should be). Password managers solve this by securely storing all your passwords behind a single master password, so you only need to remember one strong passphrase instead of dozens of random strings. Most password managers can also generate new random passwords directly and auto-fill them into websites and apps, which removes the temptation to reuse the same password across multiple accounts — a habit that turns a single data breach into a much bigger security risk.
Even the strongest password can potentially be exposed through a data breach, phishing attempt, or malware on a compromised device, which is why two-factor authentication (2FA) is widely recommended as an additional layer of protection. 2FA requires a second piece of verification beyond your password — typically a code sent to your phone, generated by an authenticator app, or confirmed through a hardware security key — meaning that even if your password is stolen, an attacker still can't access your account without that second factor. Enabling 2FA on your most important accounts (email, banking, password manager) alongside using strong, unique passwords gives meaningfully stronger protection than a good password alone.
How long should my password be? Most current security guidance recommends at least 12-16 characters for important accounts, with longer being better where a site allows it. Some critical accounts (like your password manager's master password or email) benefit from being even longer.
Is it safe to generate a password on a website like this? Yes, in this case — the password is generated entirely in your browser using JavaScript and is never sent to a server. That said, always be cautious about which sites you trust for this, since a malicious site could theoretically log what's generated.
Should every account really have a different password? Yes — reusing passwords means that if one site suffers a data breach, attackers can try the same password on your other accounts, a technique called credential stuffing. Unique passwords per account contain the damage to just that one site.
Are symbols necessary in a strong password? They help, but aren't strictly required if the password is sufficiently long. Some sites still require at least one symbol or number, so including a mix generally satisfies the widest range of password policies.
Do longer passwords slow down login on purpose? No — a long random password is just as fast to use as a short one once it's saved in a password manager with autofill, so there's no real usability downside to maximizing length.
Can I exclude ambiguous characters like 0, O, l, and 1? Many password generators offer this as an option to avoid confusion when manually typing a password — check the settings above if this feature is available for your generated password.
